A novel bandwidth-enhanced dual-polarized antenna (BEDPA) with symmetrical closed-resonant-slot pairs for 2/3/4G and international mobile telecommunications bands is proposed. The BEDPA is realized by etching closed slots symmetrically on the conventional cross-dipole broadband dual-polarized antenna to increase a new resonant mode in the higher band. As simulation and experiment indicated, the BEDPA obtains an impedance bandwidth of 67.3% (1.4 - 2.82 GHz) for VSWR < 1.5, which is 11.5% wider than the conventional cross-dipole broadband dual-polarized antenna, and a high port-to-port isolation (ISO) > 38 dB. Over the operating frequency, the BEDPA achieves a stable radiation pattern with a half-power beamwidth (HPBW) within 64.5 +/- 4.5 degrees, a gain within 8.9 +/- 0.7 dBi, and a cross-polarization discrimination (XPD) > 22 dB. Furthermore, a linear array with an impedance bandwidth of 73.1% (1.37 - 2.95 GHz) and an ISO > 27 dB is fabricated for the active antenna unit application. The linear array achieves a HPBW within 64 +/- 6.5 degrees, a gain within 16.5 +/- 1.5 dBi, a sidelobe suppression (SLS) > 16 dB, and a front-to-back ratio (F/B) > 24 dB. |
